WATERPROOF MATERIAL.

1,924,135. Specification of Letters Patent.

Application filed April 18, 1911.

Patented Apr. 23, 1912. Serial No. 621,933.

To all whom 2'25 may concern:

Be it known that I, FERDINAND JACOB, merchant, a subject of the German Emperor, and residing at 23 Neumarkt, C0logne-onthe-Rhine, Kingdom of Prussia, Germany, have invented a certain new and useful Waterproof Material to be Employed in the Manufacture of Articles of Any Kind, .such as Clothing, Tents, Covers, Tall-Coverings, and the Like, of which the following is a specification.

The present invention relates to a waterproof material, which is'to be used in the manufacture of articles of any kind, such as clot-hing, bed covers or sleeping sacks, tent covers, wall coverings and the like and must besides being impregnable to water, meet the indispensable requirement of being well porous and allowing of an easy ventilation, and be cool during the warm season and warm in the cold season.

For attaining the above stated conditions the present invention provides that the one side of the surface of a porous and therefore easily ventilated textile fabric of suitable material, such as wool, cotton, jute, hemp, linen, silk or the like is covered with a uniformly distributed coat or layer of preferably animal feathers, so that these will cover the entire area of the material and adhere well to the latter but will not prevent the passage of air through the structure of the fabric. This is obtained by the feathers being arranged like scales over and if necessary also beside each other and secured to the fabric at one of their ends only, preferably the quill end, and not at the same time at the other, the point end, so that this latter end may be readily lifted or rest loosely movable on the fabric. If now by some cause or other water or moisture penetrates to the feathers of the material lined with them, such water will run off in small drops along the side of the feathers turned toward the material and reach the second row of feathers, whence it will pass the several rows of feathers until it reaches the last row and from here drips to the ground and be again evaporated. Articles made after this manner, such as clothing, covers, tent cloths and the like are particularly suited for use in tropical countries as they will safely prevent moisture from penetrating from outside and yet admit of a free circulation of air, and as the feathers will keep off heat and cold.

In order to make my invention more clear,

I refer to the accompanying drawing, which similar letters denote similar parts throughout the several views, and in which- Figure l is a representation of the complete garment; Fig. 2 is a front view of a single row of feathers; and Fig. 3 is a transverse section through two rows of feathers on the fabric.

For lining the garment c with a material a prepared according to the method forming the subject matter of the present invention strips of fabric f forming a fold in cross section are sewn or otherwise secured at their upper edge to the inside of the mate rial a intended as a lining for the garment 0, such strips being arranged at a distance from each other, which is a little smaller than the almost uniform length of the feathers 6 which are preferably taken from water fowl such as ducks, gulls, geese and the like. In these strip-folds the feathers are secured in such a manner, that they slightly overlap at their edges. The feathers are secured preferably at their quill ends and by any suitable means. They are preferably secured in such a manner, that the feathers are pasted on by means of a glue introduced into the fold of the strips f, say a solution of gum arabic, as this method has the advantage of greater durability than if the feathers were sewn on. When arranged above each other the points of the feathers will overlap the strips f.

I claim:

1. Waterproof material to be used for the manufacture of articles of any kind such as clothing, tent cloths, covers, wall coverings, and the like consisting in the fabric to be protected against the entrance of the air being provided with a layer of feathers entirely covering this fabric, the said feat-hers arranged to overlap in the manner of scales and attached with their upper end to the fabric only, their lower ends being loosely liftable and resting easily movable on the fabric.

2. Waterproof material to be used for the manufacture of articles of any kind such as clothing, tent cloths, covers, Wall coverings, and the like consisting in the fabric to be protected against the entrance of the air being provided with a layer of feathers entirely covering this fabric, the said feat-hers arranged to overlap in the manner of scales and attached with their upper end to the fabric only, their lower ends being loosely tlrely covering liftable and resting easily movable on the fabric, the feathers arranged in rows overlapping each other like scales from above and the sides and secured with their quill ends to folded strips of fabric secured in suitable manner at their upper edge to the fabric at distances corresponding to the length of the feathers.

3. Waterproof material to be used for the manufacture of articles of any kind such as clothing, tent cloths, covers, wall coverings, and the like consisting in the fabric to be protected against the entrance of the air being provided with a layer of feathers enthis fabric, the said feathers arranged to overlap in the manner of scales and attached with their upper end to the Copies of this patent may be obtained for five cents each, by addressing the fabric only, their lower ends being loosely liftable and resting easily movable on the fabric, the feathers arranged in rows overlapping each other like scales from above and the sides and secured with their quill ends to folded strips of fabric secured in suitable manner at their upper edge to the fabric at distances corresponding to the length of the feathers, the feathers secured in said fold by means of a layer of glue introduced therein.

In testimony whereof I hereto aflix my signature in presence of two Witnesses.
